How much time does it take the pendulum bob to reach its highest speed?

Take free fall acceleration to be = 9.80 .

How much time does it take if the pendulum is released at an angle of instead of ?

**drwls**, Thursday, April 15, 2010 at 4:38amThe time to reach maximum speed after release is the time it takes to reach the lowest elevation, which is 1/4 of the period. The period is

P = 2 pi sqrt(L/g) = 0.977 s

1/4 of that is 0.244 s

Note that it is independent of how far up the pendulum is pulled
